Up for sale is an Arturia KeyStep Pro in excellent condition, fully tested and working as it should. All keys, knobs, buttons, and touch strips respond properly. Comes with the original power supply.

Reason for sale: It's a fantastic unit, but my workflow has shifted toward driving my setup from drum machines and percussion-based sequencing, so it isn't getting the use it deserves.

The KeyStep Pro is a powerhouse controller and sequencer for any studio, live rig, or modular setup. It gives you four independent tracks (three melodic plus one 16-lane drum track), each with its own sequencer and arpeggiator, so you can run multiple synths and drum machines at once from one unit.

Highlights:

  • 37 slim keys with velocity and aftertouch
  • 4 polyphonic sequencer tracks with up to 64 steps per pattern
  • Arpeggiator, scale, and chord modes on every track
  • Pitch and mod touch strips
  • CV/Gate/Mod outputs for all 4 tracks, plus 8 drum gate outs for modular
  • 2 MIDI outs, MIDI in, and USB MIDI
  • Clock in/out, metronome out, and sustain pedal input

A perfect brain for a Eurorack system or a hands-on hub for hardware synths and DAW control.

Included: KeyStep Pro, power supply

Ships well packed. Feel free to message with any questions!
